Specification of Letters Patent.

Patented Jan. 14, 1908.

Application filed March 13. 1907- Serial No. 362-213- To all whom it mayconcern:

Be it known that l, Janus (l. Suioxsox. a citizen of the United States,residingat Rockford, in the county of \Yinnehago and State of lllinois,have invented certain new and useful Improvements in Motor-Yehicles, ofwhich the following is n specification.

The object oi this invention is to lessen the shockorjarimparted to therear portion of a motor vehicle. This I accomplish by the employment ofa truck connected ahoutnnidway of its length to the rear portion of themotor vehicle, and employing carrying wheels for each end of the truck.

The further'ohject of this invention is to distribute the weight or loadon six supporting wheels instead of tour as heretofore em plo ed.

he further ob'ect of this invention is .to construct a six w ieeledmotor vehicle, four of the wheels controlled b the steering apparatus,and four of the wheels supporting a truck which supports the rearportion of the vehicle.

In the accompanying drawings. Figure 1 is a vertical lengthwise sectionon dotted line a a Fig. 2. Fig. 2 is an underiace View. Fig. 3 is atransverse vertical section on dotted lines b b'Fig. 2.- Fig. 4 is atransverse vertical section on dotted line 0 c Fig. 2. Fig. 5 is a diaram illustrating the manner of connecting t 1e steering wheels.

In the drawings 1 have shown my improven'icnts in connection with theplatform of a motor vehicle, the body and motor parts not, being shown,as m improvements relate to the supporting oi" the platform and steering arrangements.

A truck 1 has two boxes 2, in this instance, secured to its upper face.A. rear axle 3 is supported by the boxes in a manner to rotate therein.Two supporting wheels 4 are suitabl connected with the axle to berolicreby. Any suitable connection can be 'made between the axle and themotive power of the vehicle. the truck is pivotally-connected a centralaxle 5 midway of its length on the pivot 6.

To opposite ends-o1 this axle are pivotally mounted the upports 7 and Sm a manner v to permit them to turn on a vertical pivot 9.

To the support 7 is connected a supporting wheel 10, and an arm 11extends inward To the support 8 18 confrom the support. neoted asupporting wheel 12, and an arm 13 extends inward from the support.

To the front end of.

To theupper [ace of the truck are pivoted two springs 11, their freeends are connected to the underl'ace of the vehicle platform 16. Fromthe undertace of the platform 16 depends a frame composed of the twovertical posts 17, a horizontal section 18 and two diagonally arrangedbraces 19. llhe forward portion of trucle 1 is located between thevertical posts 17 which serve to hold the truck from ateral movement, orin other words, it is held in the lengthwise direction of the latform.To the under-face of the forwar end of the platform are two springs 20,and to the springs is secured an axle 21. To 0 posite ends of this axle21 are ivotall y mounted the wheel supports 22 an 23,in a manner toermit them to turn on a vertical pivot 24. o the support 22 is connecteda bell-crank composed of the arms 25 and:26, and to the sup ort 23 isconnected. a bell crank composed of the arms 27 and 28. A rod 29connects the arms 11 and 25, and a rod 30 connects thearms 13 and 27.Brace rods 31 connect the axles 5 and 21.

To the underface of the platform is supported a toothed rack 32 -by' theboxes 33 in a manner to permit the rack to have a bodily slidingmovement in the direction of its length. v

To the platform is pivotally su ported a. steerin lever 34, its lowerend having a toothed se ment 35 connected to it and which 111051 183with the toothed moi; 32.'j

This steering wheel im arts a reciprocating movement to the toot liedrack. In bearings 36 connected tothe underside of the platform is suported a rock-shaft 37, and

to this rock-sha tis fixedly connected an arm 38 which has a connectionwith the toothed rack 37. To the rock-shaft is connected an arm 39, tothe free end of which are con nected two rods 40 and 41, the rod 40 haslever connected to the wheel support 22 and a connection with the arm26, the bell-crank 1 the rod 41 has. a connection with the arm.

28 of the bell-crank-lever connected to the wheel support 23. Wheels 42are connected to thesupports 22 and 23.

By means of the steering lever the wheel supports 22 and 23 are turnedon their pivotal connection. with-the axle 21. This turning movement. ofthese wheel supports. will turn the wheel supports 7 and 8 through,

the rods 29 and 30, so that all four'front wheels will be turned at thesame time to either the right or left.

20 i of that end of the rod will be equalto the movement of the forwardend of the rod.

/ 11 and'25 of the wheel supports 7 and 22 on one side of thevehiclemaybe ascertained. Aline 43 is continued indefinitely through the'rear' axle 3Q The forward wheel 42 is turned at any 'ven angle and-aline 44 is extended at ri tangles -to the face of the .wheel until itintercepts the line 43, which will be at the point 45, A line 46 is thendrawn from the pivot point of the wheel support 7 to the point 45, andthe wheel 10 is then located at right angles to the line 46. A given leth being allowed the arm 25 of the front w eel: sup ort 22, and the rod29 being of adength su hstantially equal to the distance between thepivotal points of the wheel supports 7 and 22, the end of the rod 29 isconnected to the arm 11 at a distance from the pivotpoint 9 so that themovement With the rod thus connected any movement imparted by thesteering apparatus to the forward wheels will impart a relative. lessmovement to the center wheels as shown by the diagram. l

The connection of the four front wheels will ermit all the Wheelstoturnwithout skid ng. l I

Bi connecting the four rear wheels to a ,truc and the truck having aconnection with the vehicle platform about midway of its 'le th, anyrisingv or falling movement. of the our rear wheels will impart aboutonehalf of such movement to the vehicle plat.- form. I '7 By pivotingthe axle 5 to the front end of the truck the axle can oscillate-so thatthe wheels supporting it can'have an independ'-. ent vertica movement toconform to the inequalities of the ground. I claim as my invention: l 1.In a motor vehicle the combination of. the platform thereof, a trucksupporting one end of the platform and connected thereto about midway ofits length, supporting wheels connected to oneend of the truck, an axlepivotally connected tg the other end of the truck on a horizontal ivot,and Exp porting wheels connected to t e pivoted e-.- 2. In a motorvehicle, the combination of the platform thereof, a truck supportin oneend of the platformand connecte 'nected to the ends a a I amiss theretoabout midway of its length, means holding the truck against lateralmovement, supportingwheels connectedto one end of the truck, anaxlepivotally connected to the other end of the truck on a horizontalpivot, and supporting wheels connected tn the pivoted axle.
